A is wrong. doubling is wrong tense.

B is wrong. cannot tack on an infinitive to connect a clause to an independent clause

C is wrong because those refers back to 20 percent (of young adults), which is singular.

D. same as C.

E. least of 5 evils. percentages is considered a number...?

I guess those correctly refers to plural (20%) because 20 percent inherits the plurality from Adults (plural)...
